Novo, M. Guglielmo, G. Ciaramitaro, P. Assennato, S. Novo, G. Coppola. - In: INTERNATIONAL JOURNAL OF CARDIOLOGY. - ISSN 1874-1754. - 225:(2016 Dec 15), pp. 402-407. [10.1016/j.ijcard.2016.09.037]
Abstract:
Background: Cardiac resynchronization therapy (CRT) is a successful strategy for heart failure (HF) patients. The pre-requisite for the response is the evidence of electrical dyssynchrony on the surface electrocardiogram usually as left bundle branch block (LBBB). Non-response to CRT is a significant problem in clinical practice. Patient selection, inadequate delivery and sub-optimal left ventricle lead position may be important causes.Objectives: In an effort to improve CRT response multimodality imaging (especially echocardiography, computed tomography and cardiac magnetic resonance) could play a decisive role and extensive literature has been published on the matter. However, we are so far from routinary use in clinical practice. Electrocardiography (with respect to left ventricle capture and QRS narrowing) may represent a simple and low cost approach for early prediction of potential non-responder, with immediate practical implications.Conclusion: This brief review covers the current recommendations for CRT in HF patients with particular attention to the potential benefits of multimodality imaging and electrocardiography in improving response rate.
